Stateful Stream Operators Patents: Top Companies & Trends 2026
Stateful Stream Operators Patents: Who Leads and Where Filings Are Headed
Concentrated at the top. The top 5 assignees account for 78.0% of all 50 records in scope, and the top 10 reach 94.0% — this is a field with a small set of repeat filers, not a broad open market. Filings begin in 2017 at 1 record and rise unevenly through the period, peaking so far at 4 records in 2025. The 2021-to-2024 span, the most recent stretch with complete publication, shows a decline from 3 to 2 filings (-33%) — read the 2025-2026 uptick with caution, since publication lags filing by roughly 18 months and those years are still filling in.

Common questions about the stateful stream operator patent landscape
Who holds the most patents on stateful stream operators?
The ranking covers 17 companies, and it is heavily front-loaded: the leading assignee alone holds 15 of the 50 records in scope, and the top 5 combined account for 78.0% of all records. Filers in this space include enterprise data infrastructure vendors, major cloud and software licensing companies, and telecom equipment makers. Because the field is this concentrated, a new filer’s practical competitive set is really just the handful of companies at the top of the ranking, not the full list of 17.
Is patent filing in stateful stream processing growing or shrinking?
Filing activity is uneven rather than steadily rising or falling. Using the most recent complete years, 2021 to 2024, filings dropped 33% from 3 to 2 records. The 2025 figure shows a peak of 4, but publication lags filing by roughly 18 months, so the 2025-2026 numbers are still incomplete and should not yet be read as a trend reversal.
What technology areas do stateful stream operator patents cover most?
The large majority of records, 84.0% of the 50 in scope, carry the G06F classification for electric digital data processing, meaning most claims are framed as general computing mechanisms rather than industry-specific applications. Digital transmission (H04L) and AI-model computing (G06N) appear in smaller shares, 10.0% and 8.0% respectively. Healthcare-adjacent classes such as diagnosis, body-fluid devices and healthcare informatics each appear in only 2.0% of records, indicating that vertical applications of stream-state techniques remain thinly claimed.
Disclaimer. This analysis is based on Patsnap Eureka data drawn from a limited snapshot of global patent records and is provided for general information and reference only. Patent data carries inherent limitations — recent filings are under-counted because of publication lag, counts may be on a record or family basis, classification and applicant-name data may contain errors or duplicates, and the underlying search query defines the scope shown — so the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
Nothing here is an exhaustive prior-art, novelty, freedom-to-operate or validity search, nor does it constitute legal, financial or professional advice, and it should not be relied upon as such. Verify independently and review with qualified patent and legal professionals before acting on it.
